Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If standard abrasion procedures are used for glass materials, then the abrasion process can be performed, but the precision in introducing flaws and controlling the abrasion distance is insufficient
Solution Approach 1:
The orifice structure is made adjustable within the funnel, allowing the offset distance of the outlet orifice from the bottom end of the funnel to be changed. This dynamic adjustment capability enables precise control over the abrasion distance between the outlet orifice and the specimen, directly resolving the precision control issue while maintaining reasonable device complexity through a simple adjustable mechanism.
2Measurement precision
If adjustable orifice structure is implemented, then abrasion distance precision is improved, but device complexity increases
Solution Approach 1:
The orifice structure is designed as a separate, adjustable component within the funnel rather than a fixed integral part. This segmentation allows the orifice position to be independently adjusted to set precise abrasion distances, while the modular nature keeps the overall device complexity manageable through straightforward assembly and adjustment mechanisms.
3Productivity
If vacuum line is added for removing spent abrasive material, then productivity is improved, but device complexity increases
Solution Approach 1:
The vacuum line is connected to the funnel to automatically remove spent abrasive material from the system during the abrasion process. This self-service capability allows continuous operation without manual intervention for clearing spent material, significantly improving specimen preparation efficiency and productivity while adding only a simple vacuum connection to the device.
